Team Tree House?

I’ve started using teamtreehouse.com since reading about it for the first time yesterday. I’m not sure how far I’ll be able to go with it because it is actually a paid program (service?) and I don’t have spare funds at the moment. I was however able to score a free first month through a promotion I found, so I’ll try to make the most of it. It is way more interactive than simply watching videos. It includes quizzes, and coding challenges that let you know if you got it right as well as the usual follow along videos I have come to know from mybringback and other sources.

I started at the beginning of the Learn Android Adventure and am just working my way through it. I have learned a few new things. They recommend always using scale-independent pixels (sp) which I think I agree with. They will scale based on the size of the screen as well as the user’s font setting for the device. If I understand correctly using density pixel would stay the same size no matter what the user had the device’s font to set to. This would potentially cause your app to be unusable by someone with poor eyesight who had the font set to large so they could read it. That would be bad.

I’m also learning about arrays! Arrays can be used to store a number of different values from one data type. You tell the computer that it is an array by using square brackets after the data type (String[]) and then open curly braces to start your list of values. That was a terrible description so I’ll just include a picture of my code for the app tree house has me making. Actually, I’m altering the app a little. They are making a Crystal Ball app, and I’m not into that, at all. So I am making an Ask Yoda app.

My First Array in Java/Android

I was excited to cover if statements because mybringback hadn’t touched on them yet and I remembered them being such a big part of the course I took on Python.  It seems like they will be a fairly big part of Android dev as well, and I imagine of any type of programming. Before we made our array as seen above we simply had 3 possible answers: Yes, No and Maybe. We had a random number generator (Which is also new for me in Android) that could give us 0, 1 or 2 when we ran it. We used this with an if statement to assign 0 to Yes, 1 to No and 2 to Maybe. This worked great and was a simple way to introduce if statements. When we added are array we pulled that if statement out. I have added a new one to my code though that changes the background color dependent on whether the answer was positive, negative or neutral.

I’ll stop there for now. I’m really liking Team Tree House. I really think I’d like to continue using it after this first free month runs out. I’m going to see if I can work it into my budget somehow. That said, if you are interested in learning anything in their library please consider using my referral link. It will get you 50% off your first month and I’ll get $5 off my next month.
